The Wall Street Journal is launching an index of the most powerful people in Greater New York—and we want to know who readers think should top the list.

Prominent New Yorkers, business and financial heavyweights and political titans from across the region will face off in the Journal's NYIndex voting app. The set-up is simple: A pair of powerhouses are put forward by the app, and you are asked to choose which boldface name holds more sway in and around the city.

Go to projects.wsj.com/nyvote to pick the most influential people in the region and share your choices in each head-to-head contest over Twitter. @WSJ will retweet some of these picks.
